HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 356,372, dated January18, 1887.

Application filed October 1l, 1886. Serial No. 215.824, (No model.)

To all whom, it may concern:

Be it known that I, JOHN H. PARKER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in IzIose Nozzles, whichare fully set forth in the following specification, reference being hadto the accompanying drawings, forming a part thereof.

Figure l is an axial section showing the device in position to throwasolid stream. Fig. 2 is an axial section showing it in position lo throwa spray, the base being shown in elevation. Fig. 3 is a similar sectionas in position to cut off the stream entirely. Fig. 4 is a perspectiveof the forward part of the base, designed to show the formation of theterminal valve or plug thereon.

A is the base. B is the tip. The former is longitudinally inserted intothe latter at the rear or inner end.

lC is the gasket or packing-ring, secured in a groove, a, iu the part A,and serving to make a water-tight bearing for the part A in the part B.The base A terminates at the rear or inner end in any proper andconvenient de vice by which it may be connected to a hosepipe. Itcomprises the cylindrical portion A, which has the longitudinal passageA1", hereinafter called the receiving passage.7 It terminates in theplug or piston-valve A2, which is connected with the tubular part by thelougitudinal diaphragm or stem A2", which does not prevent the passage Adischarging freely about the plug. I prefer the form illustrated,because it can be most cheaply constructed, the entire base A, includingthe plug A2 and the connectingstem A20, being easily cast in one pieceby the use of a core, and requiring no work except lathe-finishing tocomplete it for its purpose. -Upon the exterior of the cylindricalportion A is formed the raised thread, or, as it may be considered,thethreaded boss All. The tip B has a longitudinal passage, hereinaftercalled the discharge-passage,7 and is interiorly threaded at 'the inneror rear portion, B', to receive the exterior thread, Au, of the baseA.The discharge passage comprises, as illustrated, three distinctportions, B2, B3, and B4, and for the purpose of its operation fully, asdesigned, the first two of these parts are essential. The portion BZ islarger in diameter than the portion B3, and when the portion B* is addedit is preferably somewhat smaller than either of the others, and mostpreferably slightly tapered, as illustrated.

The portion B3 is provided with an interior groove or grooves, b, whichin the illustration are strictly spiral, being in the form of a doublethread commencing at the end of the portion B2 and extendingcontinuously to the commencement ofthe portion Bf. rIhe plug orpiston-valve A2 is of such diameter as substantially to close theportion B3 of the discharge-passage when it is located therein, exceptas to the grooves b3 in the wall of said passage, said plug A2 having nothread or projection to enter said grooves, but, on the contrary, beingstrictly cylindrical. The forward end, however, of said plug may becrowning, or conical, or slightly beveled, and the entrance to theportion B4 of the discharge-passage is preferably dressed to form a seatfor said plug, so that when the plug reaches the seat it may completelyclose the discharge passage by seating at that point.

The operation of this structure is as follows: When the device is in theposition sh'own in Fig. 1, the water entering through thereceiving-passage A1" passes out by the stem A20 into the portion B2 ofthe discharge-passage, and therein passes around the plug A2 and thenout through the portions B3 and B4, being discharged in a solid stream.Vhen the device is adjusted to the position shown in Fig. 2, the waterpasses, as before, into the portion B2 of the discharge-passage, but canescape thence only by following the oblique or, as the 'case may be,spiral passage afforded by the grooves b3 in the wall of the portion Biof the dischargepassage, and in following that course it acquires anoblique movement,which, owing to the circular character of the remainderof the passage, becomes a spiral movement, whether such is the form ofthe grooves or not; and this movement, giving to it al centrifugalimpetus, causes, as soon as it is beyond the confining-walls of the tip,each particle of water to follow a course divergent from the axial lineof its spiral movement, and it is thereby converted, first, into aconical film or sheet of IOO water, the apex of the cone being at thetip of the nozzle, and next, at a short distance from the nozzle, into afinely-divided and .widelydistributed spray. Vhen it is desired to shutoi` the water entirely, the parts are adjusted by rotating the tip, orthe base, as is most convenient, until the plug seats at the entrance tothe portion B* ofthe discharge-passage.

In order to fix delinitely the point at which the base and tip should beadjusted in order to throw a solid stream, and to prevent unintentionalseparation of the two parts by screwing the tip too far forward whenthus adjust ing it, I provide the screw D, which is set through theshell of the tip at the inner or rear end, and, after the two parts havebeen screwed together, may be screwed in, so that it will at` ford astop for the end c of the thread A and prevent the base being screwedentirely out of the tip. This screw will be stopped by its head fromentering so far as to bind upon the outer surface ot' the cylindricalportion A.

I do not design to liinitmyseli to the use of the strictly spiral grooveb3; but any oblique groove in the wall of the portion B ofthedischarge-passage would produce the-effect designed. Such groove wouldnecessarily be spiral unless made irregular, and any irregularity couldhave no eiiect except to retard the current, andto that extent would lieundesirable. I prefer, therefore, the strictly spiral groove.

I do notlimitmysehF to the relative position and arrangement shown ot'the two parts B2 and B and the val ve-seat b", for it is obvious thatprovision might be made for seating the valve between the parts B2 andl.

I do not limit myself' to connecting the two parts, base A and tip B, byscrewing them together, though I consider this by far the best method;but they might simply slide one within the other, and be provided withany means for fastening them at the several posi tions for producing thedescribed different rcsuits.

I claiml. A hose-nozzle comprising a dischargel passage having a largerportion, a smaller portion, and a dual-discharge portion, the secondmentionedportion being interiorly grooved in oblique direction, incombination with a plug or valve movable longitudinally in saiddiscliiarge-passage and closing the grooved portion, exceptas to thegrooves, when it is 1ocated therein and seating beyond the groovedportion at the entrance to the final-discharge portion, substantially asset forth.

2. In combination with the nozzle-tip having a valve-seat., and adischarge-passage comprising a larger and asmaller portion, the latterbeing interior-ly obliquely grooved, a base having the receiving-passageand terminating in a plug or valve having a cylindrical body which fillsthe grooved portion otl the passage, except as to its grooves, andhaving an annular seating surface which tits the valve-seat, saidannular seating'suri'ace being located rclativel y to the cylindricalbody as the valve'seat is relatively to the grooved part of thedischargepassage, whereby the valve seats at the limit of its movementint-o said grooved portion, substantially as set forth.

In testimony whereof I have hereunto set my hand, inthe presence of twowitnessesI- this 7th of October, A. l). 1885.
